In “VOIP Accounts” dialog the toggle does not deactivate the account
In Gnome Calls 43.0-43.0 in the VOIP Accounts dialogue I have two accounts with a toggle after each. When I toggle one of the account, the switch changes its color blue⇔grey, and the system says “Account is online” or “Account is offline”.
When I toggle the other account, the switch moves left⇔right, but the background stays blue and there are no messages (tooltips with × button) “Account is online” or “Account is offline”. What does the toggle behind that account do, if it does not bring the account offline?
